The World Health Organisation has recently updated it’s guidance on the use of Masks to combat Coronavirus.
They are now recommending that non-medical masks should be worn where there is widespread transmission and when physical distancing is difficult, such as on public transport, in shops or in other confined or crowded environments.
There still seems to be concern that encouraging the public to wear masks will also encourage the public to behave irresponsibly:
“I cannot say this clearly enough,” said the Director-General. “Masks alone will not protect you from COVID-19.”
